Renal epitelial neoplasia associated with Kimura disease

To present a case of Kimura disease associated with kidney epithelial neoplasia. Kimura disease is a rare inflammatory disease, which usually presents with enlarged lymph nodes and masses in the head and neck regions. The differential diagnosis should include lymphomas, reaction lymphadenopathy to drugs or parasites. Amid the masses and enlarged lymph nodes a nodule suggestive of neoplasm can be found. There is a case, in the literature that describes Kimura Disease associated with kidney neoplasm.

We present the case of a young female patient who showed intra and retroperitoneal nodulations, including one in the lower pole of left kidney. After the period of treatment with corticoids, computed tomography of abdomen confirmed the permanence of the lesion with features of malignancy. A partial left nephrectomy was performed, and postoperative evolution was favorable.

The patient is without signs of Kimura Disease and no signs of recurrence of the tumor after a period of 18 months from surgery.

Kimura disease is associated with some neoplasias that should be investigated by the medical team. Partial nephrectomy seems a good therapeutic option for well-defined neoplastic nodules located on renal poles.
